Infrared Manual Focus Lens Description:
Focal Length 50mm F0.8 Infrared Manual Focus Lens For 1024x768-17um Detector.
8-12um Long Wave Infrared Germanium Lens Apply to Infrared Sight Scope, Thermal Imager, Monitor Camera, Drone Monitor, Thermal Sight, etc.
Features of Infrared Lens
1) Night vision in low-light conditions: When it comes to seeing in the dark, the light we receive from the atmosphere is mainly found in the SWIR band range of 1.0-1.8um. This makes LWIR night vision imaging more effective than using visible light. It has some great advantages, like being able to capture details even in deep shadows and being able to see through window glass. This makes it perfect for use in dark places or at night.
2) Simple optical setup: LWIR light can easily pass through glass, so a LWIR camera doesn't require a special housing. It only needs a protective window glass, which gives it a lot of flexibility when used on a specific platform or occasion.

FAQ:
What is AR Coating?
Anti-reflective coating (Anti-reflective coating, AR) is a surface optical coating that increases transmittance by reducing light reflection. In complex optical systems, it can improve contrast by reducing scattered light in the system.
Many coatings include transparent thin film structures with different refractive indices. The thickness of the film determines the wavelength of reflected light it acts upon. When light is reflected twice on the AR coating, it interferes with the original reflected light, thereby weakening the reflected light. According to energy conservation, the energy of light is constant. Thus, as reflected light decreases, transmitted light increases. This is the principle of AR coating. Generally speaking, when choosing an AR coating, it is necessary to determine the wavelengths, such as infrared, visible and ultraviolet.
